i installed my aem wideband to my s300 and now for some reason the tps display is red and stays are 0 not letting me go over 2000rpm
if i hold the gas at 2500, rpms will drop and rev up again

also i cant seem to get my s300 to read the same as my wideband does.
the white output from aem goes to the eld wire on the ecu.
eld is selected on s300


any ideas?

 

The s300 is not the issue.

Make sure you actually wired the input to the CORRECT pin on the harness.
Make sure you removed the correct resistors you claim you did r136 and r138 & not r137 in the middle which is a tan colored resistor.

 

yes r136 and r138 were snipped the middle one was left alone.
but for some reason i cant get it to be as accurate as the gauge. its barely moves in value while the wideband is totally different..

also the tps problem only started after i snipped the 2 and i have soddered them back and nothings changed

 

oh yea with the Key on engine off the tps stays in the green. once the car is started it goes red

 

Sounds to me like you tapped into the wrong wire(s)

You need to do the following:
1. Review http://www.phearable.net/tech/wiring...schematics.gif
Make sure you actually cut the ELD wire & ran the 0-5 volt white wire from the wideband output to the ELD pin at D10
2. With the key on but engine off, measure the voltage at pin D11
You should see .45 or .50 volts.
3. With the key on but engine off, have some one hold the throttle down on the car.
Measure the voltage at pin D11. You should see around 4.5 volts

 

okk thanks ill give this a try later on today
